Introduction

Standard audiophile grade clocks with excellent phase noise performance and competitive price. Default configuration for FifoPiQ7 III and TransportPi Digi Pro. Great for all audio applications that require enhanced clocks.

Features

  1. Ultra-low jitter audio clock.
  2. Dual shield cans on both top and bottom side of PCB for the best possible EMI noise suppression.
  3. Enhanced internal noise filtering networks for a cleaner power supply.
  4. 3.3V ultracapacitor or battery direct power supply would be preferred to improve the performance.
  5. Featuring an OE standby function.
  6. One-year limited warranty.

Operation Notes

  1. Reversing the installation orientation will result in permanent damage to the clock, which is not covered by the warranty. Please pay exercise caution when installing the FemtoMck clocks.
  2. The pins of the FemtoMck clock are machined from solid-core copper and are gold-plated. Exercise extreme caution during installation, as these pins are prone to breaking if bent. Broken pins are not covered by the warranty and will incur re-work and re-testing fees. Damage to the shield can will also void the warranty.
  3. FemtoMck crystals require an extended period to achieve optimal phase noise performance. For new clocks, please refrain from serious listening until they have operated continuously for more than 24 hours. Further improvements can continue to develop over weeks or months of continuous operation.
  4. Power supplies are crucial for maintaining the FemtoMck's optimal phase noise performance and sound quality. Linear power supplies may serve as an entry-level option. The best power supplies are direct ultra-capacitor supplies or LiFePO4 battery supplies. Below is a list of recommended power supplies for FemtoMck, ranked by performance.
    #1: UcPure Pro 3.3V with 3000F ultracapacitors
    #2: LifePO4 Mini Pro 3.3V with UcConditioner 3.3V
    #3: PurePi 3.3V with UcConditioner 3.3V
    #4: LifePO4 Mini 3.3V or PurePi 3.3V
    #5: LinearPi/Pro 3.3V with UcConditioner 3.3V
    #6: LinearPi 3.3V
